Separation results, as they are usually understood, refer to conditions under which a firm's production decisions are independent of its risk attitudes. Well-understood situations where separation occurs typically include those where technically feasible production opportunities are replicable in financial markets. This paper gives necessary and sufficient conditions for separation that go beyond these well-understood spanning conditions. To do so, we present a unified treatment of the production and financial decisions available to a firm facing frictionless financial markets and a stochastic production technology under minimal assumptions about the firm's technology and objective function.Our main analytical tool is the derivative-cost function, which gives the minimum cost of achieving a state-contingent return vector through a combination of production choices and trade in financial assets.
